  4. The Existing Situation Information Phase The existing plant is unreliable plant and has the following problems: • Type of membranes (HFF) is obsolete. • There are reliability concerns. • High maintenance cost comparing with other RO plant. • More chemical consumption. • The other water treatment plants (old plants) will be demolished due to aging. CEM-512 VALUE ENGINEERING

  5. Information Phase A company has decided to upgrade the existing water treatment plant the (RO Plant) to overcome the existing problems and to produce 1000 gpm industrial water instead of 400 gpm. CEM-512 VALUE ENGINEERING

  6. Information Phase Objectives or required Criteria • Expand the existing water treatment plant by providing 16 new RO Units. • Use new type of membranes. • Minimize the chemical consumption. • The plant production should meet the required water quality. CEM-512 VALUE ENGINEERING

  7. The original Design Information Phase • Install additional pretreatments Equipments. • Install 16 RO Units using SW Membranes to reduce water TDS to 20 ppm. • Install additional 4 Deminalizers to reduce the TDS to less than 5 ppm. • Install new Deaerator to remove gases.

  18. 0 20 13,000 1,000,000 30,000 Development Phase The original Life cycle of Deminilizers The Initial Cost of Deminilizer = $ 1,000,000 Annual maintenance cost =$ 13,000 Salvage value = $ 30,000 Interest rate = 5% Service life = 20 years Then, P = 1000,000+ 13000(12.4622) – 30,000 (0.3769) = $ 1,150,702.0 CEM-512 VALUE ENGINEERING

  19. Development Phase Item Total Cost CEM-512 VALUE ENGINEERING $ 4,000,000 Original: Install 4 Deminilizers. Proposed:Eliminate the deminilizers $ 0 Saving in Initial Cost = 4,000,000 Original Life cycle cost = 4,602,808 Proposed Life cycle cost = $ 0 Saving in Life cycle cost = 4,602,808

  20. 0 20 6,000 500,000 12,000 Development Phase The original Life cycle of Deaerator The Initial Cost of Deaerator = $ 500,000 Annual maintenance cost =$ 6,000 Salvage value = $ 12,000 Interest rate = 5% Service life = 20 years Then, P = 500,000+ 6000(12.4622) – 12,000 (0.3769) = $ 570,251.0 CEM-512 VALUE ENGINEERING

  26. Development Phase Value Study Proposal VE team recommended the following proposal to design the water treatment plant:-1. Use sea water membranes.2. Eliminate the deminilizers. 3. Eliminate the deaerator.The final product of sea water SW membranes will meet the requirement of water quality (TDS will be less than 5 ppm). Also, the new plant production which is 1000 gpm will not be affected by this change.Using sea water membranes will increase the initial cost of the membranes by $ 800,000 but will eliminate the need for deminilizers and dearteator.

  27. Development Phase Proposal Advantages CEM-512 VALUE ENGINEERING 1. Reduce the initial cost2. Eliminate unrequited equipments.3. Minimize chemicals consumption.4. Reduce the maintenance cost.5. Safety.

  28. Implementation Phase 1. How should it be implemented? VE proposal will be discussed with the engineering and project team to remove any roadblocks prior to management presentation 2. What should be changed and in what sequence? The proposed case will be discussed with engineering team. 3. Who should do it? Engineering department. 4. How long should it take? 5 months 5. Any deadline required? Before issuing the IFC package. CEM-512 VALUE ENGINEERING
